Vacuum Harness HVAC: Description and Operation
Engine vacuum systems a pre-assembled harness which features colored nylon vacuum lines. The color is a visual aid both in production and in
service. The emission decal on the engine provides a colored schematic of the vacuum hookup which corresponds with the pre-assembled harness.
Vacuum hose harnesses consist of nylon hoses a .150 inch outer diameter and a .090 inch inner diameter bonded to nylon or rubber connectors.
Occasionally a rubber hose may be connected to the harness. The nylon connectors have rubber inserts to provide a seal between the nylon connector and
the component connection.
